2. Include the code examples as embedded snippets in the tutorial page instead of external links to p5 editor

Expected Behavior

If the tutorial is able to work with p5 2.0 with minimal changes, we want to update the code examples and
include them as embedded snippets in the tutorial page instead of external links to p5 editor.

Thanks for flagging this. The context and reasons for it not working are here: ml5js/ml5-next-gen#244

Updates to this tutorial could be done by an ml5 contributor or user; @gohai can you confirm if updates to this tutorial (v2 or v1) will be made by you / someone from ml5, or if this should be opened to volunteers? If opened to volunteers, would you or someone from ml5 be willing to help review? Thanks in advance!

Hi @ksen0, I'm writing here to confirm we'll have someone from the ml5.js team work on updating the tutorial. Stay tuned!
